This is a daddy long-legs spider. It is actually a spider and not harvestman. Looks like there are eight new species in the southeastern U.S. based on the research of :Dr. Bernhard A. HuberAlexander Koenig Zoological Research MuseumAdenauerallee 160, 53113 Bonn, Germany

"I am slowly starting to see an end of my work on my humongous Pholcus project, I think I can finish the morphological/taxonomic publication (with about 115 new species and over 70 redescriptions) next year, then I will focus on the molecular/phylogenetic part. US material will be part of both studies, and I have been thinking of starting up a project focusing entirely on US Pholcus. The diversity and biogeography there is quite amazing, but at the same time species limits are partly not easy to infer from morphology. Females are mostly indistinguishable, and I am not sure if all the differences in male genitalia do really reflect species limits.

Attached are two slides from a talk I gave some time ago. From that I would think that your photographed specimen from Lookout Mountain is most probably "Pholcus sp. B", but as I said, females are indistinguishable, even with cleared preparations of the genitalia."
